title: Infectious crystalline keratopathy caused by Pseudomonas fluorescens.
abstract: OBJECTIVE
  To demonstrate a case of infectious crystalline keratopathy (ICK) caused by Pseudomonas fluoresecens (PF).
  
  
  METHODS
  Case report description.
  
  
  RESULTS
  A 15-year-old female contact lens wearer presented complaining of eye pain and redness in the left eye. The patient reported that she had suffered a corneal scratch a few months earlier, which was treated by her family physician, and that she had felt some discomfort since then. The biomicroscopy showed a central corneal abscess with a crystalline appearance, stromal edema, the Tyndall effect, and abundant fibrin in the anterior chamber. A diagnosis of ICK was made. The culture was positive for gram-negative PF. Pseudomonas fluoresecens was sensitive to cephalosporins, quinolones, and tobramycin.
  
  
  CONCLUSIONS
  No cases of ICK caused by PF have been reported previously. Two previous studies reported that the gram-negative Pseudomonas aeruginosa caused ICK. Unlike other ICK cases in which there is minimal stromal inflammation, the patient presented with an intense inflammatory reaction in the anterior chamber.
